“When a man’s partner is killed, he’s supposed to do something about it. It doesn’t make any difference what you thought of him. He was your partner and you’re supposed to do something about it. And it happens we’re in the detective business. Well, when one of your organization gets killed, it’s-it’s bad business to let the killer get away with it, bad all around, bad for every detective everywhere.” ~ Spade
